Yeah, the field of audio is sadly full of charlatans. Look at the "time alignment" crowd. What a sales pitch! When I see a loudspeaker company that uses "time aligned" in their sales rhetoric, I write them off as snake oil salesmen.
Many internet forums are full of sockpuppets and shills, so they're a natural home for charlatans and snake oil salesmen. But I can't help but think there must be some good ones. I'd like to know what sites you guys have seen that are pretty good. Maybe we should make a list of the good websites, and another list of those to avoid and why.
